    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iron and steel industry; energy efficiency; CO2 emissions; fuel substitution; fuel switch; excess heat; biomass gasification; bio-syngas; synthetic natural gas; SNG; energy market scenarios; energy management; barriers; driving forces; järn- och stålindustrin; energieffektivisering; CO2-utsläpp; bränslebyte; överskottsvärme; restvärme; förgasning; bio-syntesgas; syntetisk naturgas; SNG; energimarknadsscenarier; energiledning; hinder; drivkrafter;

    Abstract : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. READ MORE

  4. 17. The role of industrial energy management in the transition toward sustainable energy systems : Exploring practices, knowledge dynamics and policy evaluation

    Author : Mariana Andrei; Patrik Thollander; Anna Sannö; Patrik Rohdin; Kornelis Blok; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy management; Practices; Transition to sustainable energy systems; Knowledge-creation; Process innovation; Incremental and radical innovations; Voluntary initiatives; Digital technologies for energy efficiency;

    Abstract : Mitigating climate change represents one of the most pressing challenges of our time. The EU has set the goal of reaching climate neutrality by 2050. The transition of manufacturing organizations is essential in reaching the EU’s goal, since industry accounts for circa 25% of the total final energy use and about one-fifth of EU’s GHG emissions.

    Abstract : Battery storage has emerged as a promising solution in various energy systems. However, challenges exist regarding the viability of batteries in practical stationary applications. READ MORE

  6. 19. Energy Efficiency in the Residential, Service and Energy Sectors : Barriers, Drivers and System Studies

    Author : Stefan Blomqvist; Louise Ödlund; Patrik Rohdin; Erik Dahlquist; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Efficiency; Barriers; Drivers; System Studies;

    Abstract : Increased energy efficiency is a prerequisite for achieving the national energy and climate goals, the goals set by the European Union, and the Sustainable Development Goals adopted by the United Nations. Close to 40% of Sweden’s total energy use and approximately 20% of domestic greenhouse gas emissions are allocated to the residential and service sector. READ MORE

  7. 20. System Perspectives on Hydro-Kinetic Energy Conversion

    Author : Katarina Yuen; Mats Leijon; Chul Hee Jo; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal energy; permanent magnet; direct-drive; in-stream power converter; load control; vertical axis turbine; renewable energy; engineering science; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Free-flowing water currents such as tides and unregulated water courses could contribute to world electricity production given the emergence of robust technical solutions for extracting the energy. At Uppsala University, a concept for converting the energy in water currents to electricity using a vertical axis turbine with fixed blade-pitch and a direct-drive permanent magnet generator is studied.
